Compared with other compounds in its class, the molecular weight of 135.16 g/mol gives (Z)-Methyl(oxido)(phenylmethylidene)azanium distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies (Z)-Methyl(oxido)(phenylmethylidene)azanium (CAS 7372-59-0), a certified reference material (molecular formula C8H9NO, MW 135.16 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, (Z)-Methyl(oxido)(phenylmethylidene)azanium is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 135.16 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
